Role of AST in CCLRC

• Core Business for CCLRC (DL + RAL)

• 40+ years expertise in electron, proton and ion accelerators

• Design, build and operate Large User Facilities• latterly photon and neutron sources: SRS ISIS

• Develop next generation solutions• DIAMOND ESS ERLP/4GLS ( ILC, NF, ……..)

• Underpinning R&D programmes

• Technology infrastructure

• Interdisciplinary skills plus operational scale


Background• R&D skill bases in Facility Departments had declined

• Accelerator Science and Technology Centre (ASTeC) created in 2001:– initially 20 staff: £750k pa

– now 55 staff (accelerator specialists only): £7-8M pa

• Centre of Expertise for R&D studies (skill base)

• Expansion through SR02 awards to CCLRC + PPARC

• Creation of PPARC Accelerator Institutes (2004)

• Daresbury Science and Innovation Campus (2006)


ASTeC Organisational Structure• Five Groups:

– Accelerator Physics (Susan Smith) (14) +1

– Intense Beams (Chris Prior) (7) +1

– RF and Diagnostics (Peter McIntosh) (18) +1

– Magnetics and Radiation Sources(Jim Clarke) (6) +1

– Vacuum Science (Joe Herbert) (7)

• Restricted to AST specialisms - not CCLRC engineering etc

• Innovative style of Sci-Tech Centre within CCLRC

– Internal income from SRS, 4GLS

– External income from PPARC, RC Basic Technology, DLS, EU…

– Funds activities in ISIS, CLF, EID - and external collaborators


ASTeC Sponsored Programmes

• Linear collider - ILC: LC-ABD

• Neutrino factory - MICE, design concepts, proton driver, muon systems, targets

• Light sources - ERLP, 4GLS, FELs

• Neutron sources - MW studies, proton driver, FETS, targets

• SRS and ISIS support role • Generic R&D (eg laser-plasma projects, FFAG)

Next Generation Light Source

• DIAMOND does not satisfy full range of UK science

• Multi-source, fs regime pulses of high brightness needed

• Linac based solution utilises ERL technology

• 4GLS design concept has evolved over 4 years

• CDR published April 2006 - TDR phase entered

• R&D challenges for maximum performance

Principal challenges:

• Beam transport optics - fs bunch compression, CSR, wakes

• High peak intensity DC photo-gun

• Upgraded TESLA linac modules

ERLP/4GLS Progress

ERLP

• Design challenges overcome - S2E simulation and engineering solutions

• Construction advanced - but delayed by commercial contracts

• Commissioning systems commenced in 2006

• Initial deliverables (eg recovery) to be completed by mid-2007 ?

• Accelerator and photon science exploitation planning

4GLS

• CDR completed (major ASTeC input)

• TDR initiated (including cost estimates) : complete in ~1 year

• Parallel R&D programme being established

This activity is crucial to the Campus Horizon - need for new CI role


Strategic Position on Light Sources• ERLP will be first energy recovery device in Europe

• Major skill base established (AST and FELs)

• World leading design adopted

• Technology challenges - performance and cost (guns, modules)

• Technology infrastructure not yet in place (eg test facilities)

• IRUVX Consortium founded and EUROFEL grant in place

• Future exploitation of ERLP to be defined (major bids ?)

Cockcroft Institute role initiated and growing


BASROC

‘Basic Accelerator Science and Radiation Oncology Consortium’

• First ever non-scaling FFAG demonstration• EMMA - construction of small electron PoP experiment

• PAMELA - prototype proton device for medical development (design only)

• Issues: resonance crossing and asynchronous acceleration

• Outline design of EMMA completed (international input)

• Use of ERLP as injector

• Basic Technology Fund awarded: (not yet public !)• EMMA - £5.6M


• Simplified technology but challenging dynamics

• Electron model - international baseline design done

• Selected lattice: - 10 to 20 MeV 42 cells, doublet lattice 37cm cell ~16m circumference RF alternate cells (1.3GHz)

• Specification of hardware started

• Proposed location - Daresbury ERLP

EMMA - A Non-Scaling FFAG Demonstrator


Proposed site for EMMA: e-FFAG Model

Build for £4M ?


Opportunities for the DL Campus

• Sustainable skill base is crucial

• Major scientific Facility is essential (ie 4GLS)

• Funding of experimental programme - prototypes

• Integrated SRF design/construction/testing infrastructure

• Construct beam test facilities• exploit ERLP investment

• add photogun test bed

• Build and operate FFAG demonstrator (EMMA)

All of these must involve Cockcroft Institute

The PPARC Accelerator Institutes• ASTeC policy is to collaborate with both CI and JAI

• Search for synergies with broad range of ASTeC programmes

• ASTeC will fund joint appointments in each Institute

• ASTeC is equal partner in CI, participates fully in management and policy issues and now shares a building at DL - CCLRC on CI Board

• CI award is £7M (2004-2012): Liverpool/Manchester/Lancaster

• ASTeC is represented on JAI Executive Committee

• JAI award is £2M (2007-2012)


Cockcroft Institute and ASTeC• Joint proposal to PPARC

“seamless involvement of HEI and CCLRC sectors”

“equal partnership of 3 HEIs and DL”

“CCLRC will align ASTeC staff working on topics consistent with the strategy and aims of the Institute, with the HEI groups in it …”

(These ASTeC staff are members of the Institute - CCLRC is a formal member)

Emphasis on added value of research links

• Grant was to Liverpool as Principal Investigator (MWP is Co-investigator)• £7M from 1/4/04 to 31/3/12 (none direct to CCLRC)

• reviews at intervals

• partners will sign a collective agreement

• John Dainton appointed as first Director

• joint appointments will be made

• Building 2 sub-lease now signed by CCLRC: ASTeC move completed last week

• Formally separate managements but many shared support services. ASTeC Director on CI Management Committee (and CEO/DCEO on CI Board)

• Actively seek joint programmes - new culture
